My Best guess is that Blizzard will be balancing the following formula
Warrior Block = Pally Block
Warrior Block = Crit Chance * (Block Amount + Crit Bonus Block Amount) + (1-Crit Chance) * Block Amount
Pally Block = Block Amount + Bonus Block Amnt
So if they balance those equations, what's wrong with that?
Parry will reduce the effectiveness of Crit Block.
Assume:
Base Block Amount = 30%
Crit Block Amount = 60%,
Parry "Block Amount" = 50%
Now you're in a world of hurt for trying to balance and you have several possible scenarios:
The system doesn't roll for a Block during a Parry: Warriors end up losing a chance at an additional 10% reduction from crit Block. Paladins don't suffer from this drawback of Parry. As such, Warriors end up behind.
You can Block during a Parry and they are additive: Warriors Lose the amount in excess of 100%. Again, Paladins don't suffer from this drawback of Parry
The system rolls for a Block during a Parry: then Parry becomes worth less to the warrior because it will lose some of the benefit during a crit Block. Again Paladin's don't suffer from this drawback.
Now lots of this can "disappear" if a Crit Block is less than 50% of damage reduction... but that would mean a crit block does less than a parry, not much of a Final Tier Mastery.
So in any of the three scenarios that Blizzard chooses to go with, Warriors end up behind because of Parry. Grats, you guys got shafted again.
